It comes after a ruling this morning in which the Irish Court of Appeal declared that current rulings against drugs such as Ecstasy and crystal meth are unconstitutional.

It means that Ireland's 1977 Misuse of Drugs Act has effectively been thrown out and all drugs outlawed under the act are now LEGAL, reports Irish radio station NewsTalk.

The court found that recent add-ons to the act were in violation of article 15 of the Constitution, making the entire act unconstitutional.

How long will these drugs be legal?

Business Insider reports that the "accidental" loophole means the drugs are legal for today only, but news outlets in Ireland report that it could be longer.

Politicians in Ireland are now planning to present legislation this evening to make drugs such as ketamine and ecstasy illegal again but they cannot pass the legislation into law until Thursday at the earliest.

It means that for today and tomorrow (at least), ecstasy will remain legal.

- previously been referred to as 'legal highs' are now, once again, legal.

This is confirmed in a memorandum: "All substances controlled by means of Government Orders made under section 2(2) cease to be controlled with immediate effect, and their possession ceases to be an offence."

The ruling was brought about by the High Court after a man who was charged of possessing methylethcathinone (a drug with similarities to mephedrone) argued that the way in which the drug was made illegal by in Ireland was unconstitutional.

Stanislav Bederev was charged for possessing the drug in 2012, but his lawyers argued that because the decision to ban the drug did not go through parliament, it was in breach in of the constitution.

What next?

The biggest upshot of the legal loophole is that anyone prosecuted under the 1977 Misuse of Drugs Act from 1977-2015 was prosecuted under a law which has now been repealed.

And in particular, those prosecuted since 2010 - the year in which methylethcathinone was made illegal - has been prosecuted after an add-on which has now been ruled to be unconstitutional.

As mentioned, it will be at least Thursday until the drugs affected by the ruling, such as magic mushrooms and ecstasy, will be illegal in Ireland again.
